    • It works!
Color: White
After several frustrating weeks trying to repair a small crack in a polyethylene hot tub Marine Sealant did the trick. The consistency was perfect to adhere and seal a small aluminum patch over the crack. It did take about a week to cure but remains pliable enough to move as the tub expands and contracts. So far so good. ... show more

    • Used on my ceramic shower joints
Color: White
So far, so good. Over the years I have caulked the joints in my shower about 4 times but always shrinks and I have to redo again. I put this in the joints between my floor and wall tiles and has held up so far

    • Sadly, it didn't work
Color: Clear
I don't know why this glue was rated so well. I got the clear. I tried it on several areas of my fountain (inside and out) that I sculpted and waited 14 days for it to cure. It leaked within an hour after turning on the fountain. It didn't work on any area I applied it to. The white stuff, another brand, that I got at Lowes worked, but I just didn't want white. It's very difficult to find clear. ... show more
